"Duplex LC" yog hais txog kev sib txuas, tsis yog hom fiber ntau. Koj tuaj yeem tau txais OS2 ib zaug -mode duplex LC cables lossis OM3/OM4/OM5 multimode duplex LC cables. Hom fiber ntau yog txiav txim siab los ntawm cov transceiver thiab cov kev xav tau txuas.
Kuv puas tuaj yeem txuas LC UPC rau LC APC?
Tsis yog. UPC thiab APC muaj qhov sib txawv endface geometry-UPC yog tiaj tus (nrog me ntsis nkhaus) thiab APC yog kaum ntawm 8 degrees. Txuas lawv ua ke tsim qhov sib txawv ntawm huab cua uas ua rau poob siab, kev xav ntau dhau, thiab muaj kev pheej hmoo rau kev puas tsuaj mus tas li ferrule.
Vim li cas kuv lub duplex LC fiber ntau txuas tsis ua haujlwm?
Feem ntau cov ua rau yog thim rov qab polarity (Tx txuas nrog Tx es tsis txhob Rx), qias neeg connector endfaces, mismatched fiber hom (ib hom cable nrog multimode transceiver los yog vice versa), incompatible transceivers, ib tug puas patch qaum, ntau tshaj cable dabtsi yog khoov, los yog ib tug UPC / APC mismatch. Pib los ntawm kev txheeb xyuas Rx fais fab theem ntawm ob sab -yog tias Tx hwj chim yog ib txwm tab sis Rx yog xoom, polarity los yog paug yog qhov ua rau.
Puas yog uniboot LC zoo dua li tus qauv duplex LC?
Uniboot LC yog qhov zoo dua rau qhov siab - qhov chaw ntom ntom uas muaj cov kab hluav taws xob ntau thiab cov cua ntws tawm. Standard duplex LC yog yooj yim dua los txheeb xyuas, tuav, thiab taug qab nyob rau hauv dav dav -lub hom phiaj patching qhov ceev tsis yog ib qho kev txwv. Qhov kev xaiv nyob ntawm koj qhov khib nyiab thiab kev tswj xyuas qhov tseem ceeb ntawm cable.
Duplex LC puas tuaj yeem txhawb nqa 100G lossis 400G?
Qee qhov 100G thiab 400G transceiver modules siv duplex LC-piv txwv li, 100G CWDM4 thiab qee yam 400G DR4+ modules. Txawm li cas los xij, ntau qhov siab - nrawm luv- ncav cuag modules siv MPO / MTP connectors rau qhov sib txuas optics. Nco ntsoov xyuas cov ntaub ntawv module kom paub meej tias hom interface ua ntej xaj cable.
